# ISRU-first base location reveals NASA commitment to resource utilization economics over operational convenience because the south pole site is chosen specifically for water ice access

Project Ignition's lunar south pole location is explicitly chosen for 'permanently shadowed craters containing water ice' rather than for operational convenience (equatorial sites offer easier access and communication). This represents ISRU-first architecture: the base is located where the ISRU feedstock is, not where operations are easiest. The source notes this is 'a stronger implicit commitment to ISRU economics than the Gateway plan, which could have operated without ISRU by relying on Earth-supplied propellant.' The three-phase timeline (robotic precursors through 2028, surface infrastructure 2029-2032, full habitats 2032+) builds toward continuous habitation dependent on local water ice for propellant, life support, and radiation shielding. This architectural choice locks NASA into ISRU success as a prerequisite for base viability, rather than treating ISRU as an optional efficiency improvement. The decision reveals that NASA's planning now assumes ISRU economics are viable at scale, not merely experimental.
